Continuous Glucose Monitors

What is Glucose?

a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates

Diabetics have trouble controlling these sugar levels, meaning they have to constantly check their levels to assure they are in a healthy zone

What is Type One Diabetes?

Type one diabetes is a disease, often called juvenile diabetes, that affects the pancreas

The pancreas produces little to no insulin, and the body’s immune system destroys the insulin-producing cells in the pancreas.

This makes patients need to constantly need to regulate their glucose levels

Patients with Type One Diabetes

•Because of this disease patients must constantly prick their fingers in order monitor their glucose levels

A Solution

A way to solve the problem many diabetics face with constant finger pricking is a continuous glucose monitor

This will help limit the amount of time patients have to prick themselves

Continuous Glucose Monitoring System

Continuous glucose monitoring enables real-time glucose display and real-time alarms

This can help improve glycemic control and quality of life in patients with diabetes

SAP Therapy

One method of continuous glucose monitoring is sap therapy

Insulin pump therapy combined with real-time continuous glucose monitoring, known as sensor-augmented pump therapy (SAP)

SAP Therapy

The sensor helps diabetics monitor their glucose levels without constant finger pricking  

Advanced functions such as bolus profiles, bolus calculators and threshold-suspend features come with this device

Potential Barriers Solutions

Incorrect expectations, usually closed loop systems

Discomfort from insertion

Low accuracy

Become more educated in the system

Use correct insertion techniques

Proper calibration and cleansing methods

SAP Therapy

Implanted Glucose Sensors

Devices that are implanted into the subcutaneous layer of the tissue

Detect and send blood sugar levels to monitoring deviceLast in body for typically 5-7 days

New Trial

Patients implanted with sensor for 90 daysImplanted by doctorTested glucose rates for each meal with sensor through a

smart app and related that to the rate taken using finger pricking methods

Sensor Accuracy

91% of sensor measurements were calculated to be within 20 mg/dl for reference glucose measurements of ≤ 70 mg/dl, 86% of sensor data were within 20% of reference glucose measurements between 71-180 mg/dl, and 88% of sensor data were within 20% of reference glucose measurements > 180 mg/dl.

Advantages Disadvantages

Lowers amount of finger pricking

Lowers risk of infectionEasier to maintain

healthier levels Stays in body for longer

Advancements

New technologies are changing the worldSoon even more sensors and systems will be created to

make life better and easier for patients with diabetes
